Routine explanation -04-unsharp_filter eliminates sharpening
This routine is 04-image-Filters-unsharp_filter.py
# 此示例显示使用guassian过滤器来消除锐化蒙版过滤器图像。
import sensor, image, time
sensor.reset() # 初始化sensor
sensor.set_pixformat(sensor.GRAYSCALE) # or sensor.RGB565
#设置图像色彩格式,有RGB565色彩图和GRAYSCALE灰度图两种
sensor.set_framesize(sensor.QQVGA) # or sensor.QVGA (or others)
#设置图像像素大小
sensor.skip_frames(time = 2000) # 让新的设置生效
clock = time.clock() # 跟踪FPS帧率
while(True):
clock.tick() # 追踪两个snapshots()之间经过的毫秒数.
img = sensor.snapshot() # 拍一张照片,返回图像
# Run the kernel on every pixel of the image.
# 在图像的每个像素上运行核
img.gaussian(1, unsharp=True)
print(clock.fps()) # 注意: 当连接电脑后,OpenMV会变成一半的速度。当不连接电脑,帧率会增加。
